If you could build an engine any way you wanted to

[John Brown]

Back in 59-60 I remember a magazine article where they bored a small block till the deck was open (no cylinder walls left) from one end to the other.... they then ground flats in the side of sleeves, pressed them in and furnace brazed the whole affair. In effect, they made a siamesed block long before they were factory available. Just depends on how much you are willing to spend and how competent your machinist is that limits what can be done.
